Question

In right triangle  RQS, angle Q is a right angle and RQ=55,  QS=48, RS=73

.What is the value of , written as a ratio?

The value of   cos S= __________.

What is the value of , written as a ratio? 

Write as fraction in simplest terms.

  

Answer 1

cos S = 48/73 which is a fraction in lowest terms since 73 is prime.

Please notice that it is unusual to see a right triangle with these measurements!!!! Not your typical 3, 4, 5 or 5. 12, 13! In all my years doing mathematics I have never seen this particular Pythagorean triple used.
